Jack closed his eyes. He felt tired. Tired and as though he'd said too much... again. He couldn't help it though, he supposed, but really that was no excuse. There was no excuse at all. He'd made the Doctor uncomfortable, he considered, and he really didn't want to do that. He wanted quite the opposite; for them to feel at ease around each other.

The last thing he expected though was for the Doctor to embrace him further, let alone kiss him.

His eyes quickly opened in surprise, and he almost faltered. Almost. Tentatively, he lifted a hand and just touched it gently against the Doctor's cheek, lifting his own head a little to return the kiss with a soft smile on his lips.

"Okay," he whispered afterwards, staying close. "Okay. Good."
